I.' This invention lrelates to means for reguf lating" the `level of the fluid inthe vats of sizing machines, and more especially tothe preventing of `a superfluousamount of the Y5 sizing fluid from entering the sizing vat. y

I amaware thatheretofore means have been employed to prevent the level of the fluid insizing vats fromv becoming too high, which means comprises an overflow chamber sizing fluid runs, and from this overflow chamber the superfluous amount of sizing' fluid is pumped into the main reservoir supplying the vat with the sizing fluid. `1,5 An object of my invention is to provide ,f means for automatically controlling the flow yofthe, lsizing fluid into the vat of a sizing machine, and atthe same time prevent evaporated steam from entering thevat.-

Another object of my invention is to profluid to enter the sizing vat of' a slasher.

Some-of the objects of invention having been stated, other objects will appear as the tion with the accompanying drawings, in

'description proceed, when .taken in connec- Referring moreparticularly to the draw-V 43 in the floaty chamber.

The numeral 20 indicates the hood which is connected to the pipe 21 for taking off the vapors from the sizing vat. All of the abovementioned parts are conventional, and a further description ofthe same is not deemed necessary. p .In the conventional Slasher there is the pipe 22 leading from the supply tank y(not shown) for supplying the sizing fluid to the vat 10.r It' is'in this pipe line that I place a 60 partof my invention for regulating the flow of the sizing fluid to the vat 10. Above the Y ,valve7 23 I place the T-member 24 to which is threadably secured the hollo-w'T-memb-er 25, and leading downwardly from this latter 55 T-member is the union 26 which is thread ably secured to the elbow'member 27, and secured to the elbow member and also connected toy the pipe line 22, is the T-member 28, all of the said members 24 and 28 being hol- 70 low .to permit the flow of the fluid therethrough.y The main pipe line 22 'extends downwardly fromthefT-member 28 into the sizing vat 10; n Y

Belowftheopening in the T-member 25 75 which leads to the member 24, there'is secured the valve seat 3() in which is seated the needle valve 31, and secured within the upper end of they member 25 is the hollow plug 32, the valve stem 33 running therethrough'and thru the packing 34 and piercing a. hole inthe nut 35, which nut is threadably securedaround the exterior ofthe plug 32, and fitting between the upper lend of the member25 andthe nut 35 is the support 36, which is forked4 at its upperend for the reception of` the lever 37, which lever is held in position yloosely by means of the bolt 38,y

and secured in one end of the lever 37 is the eye-bolt 39V which adjustably. secures the valve stem 33' to the lever, and in the other end of the lever 37 is' a similar eye-bolt 40 which 4adjustably secures the float rod 41 to fthe lever p37.' n

` This float yrod 41 extends downwardly into a -oat chamberf42 vandy is secured to the float This float vchamber is secured to the vat 10 by means of the pipe 44 which' is connected to and com municates with the lowerportion of the float chamber, and this pipe 44'is threadably se the float 43 to have a tendency to remain at a point approximately on a level with the top of the fluid in the vat l0.

In addition to the vfloat controlled means for limiting the amount of fluid which may enter into the vat, I have provided additional means to affect the levelof the sizing fluid, which consists of improved means of introl ducing the steam into the coil of piping in the bott-om of thevat. I-Ieretofore the steam has been introduced into one side only ofthe vat, and this has caused one side of the fluid to be heated to a greater degree than the other side. I have provided means .for introducing the steam into both sides of the vat and in this way both sides of the'vat are heated to the same degree. rIhe steam is introduced by leading the steam intake pipe l45 into the larger pipe 46, the larger pipe extending downwardly, and from the top portion of this larger pipe there extends Vupv wardly and inwardly the pipe 47, which pipe 47 is connected by suitable connect-ions to the pipe 48 which runs to both sides of the ployed, they-are used in generic and descriptive sense only, and not forV purposes of limitation, the scope of the in'ventionbeing set forth in the appended claim.

I claim:

In a slasher, a sizing vat throughv whichl material is adapted to be passedto have size ing applied thereto, a source of' sizing sup'- 'ply, a pipe connected to said source of sizingsupply and extending tothe vat, a pipe lleading'froni one lside'of the vat at a point below the ordinaryl level o f the sizing fluid, said pipe leading intoja floatjchamber, a float' mounted in said float chamber, a, valve inthe pipe leading-from the source of sizing 8O yto another predetermined point.

In testimony ywhereof I affix my signature..

vat and connects to the downwardly extend# i ing pipes 49 and`50, thesel pipes 49 yand 50 being connected to the U-shaped perforated pipe 51, thus allowing the live steam to es cape thru the pe'rforations in the pipe 5l. If the pipes 45 and`47 were connected directvoo ly together, as has heretofore been done, it would mean that a large quantity of condensed steam would be introduced into the vat with the live steam, but by providing the larger section 46, and leading the larger section for some distance to a suitable steam` 'the vat and rmixing with the sizing fluid.

vIn the old method of controlling the level in the vat wherein the overflow was allowed to flowinto an overflow chamber and from,

thence pumping it back into the supply tank, it was not necessary and imperative to pre- Avent this great amount lof condensedsteam from entering the vat, but-with my improved means of regulating the level in the vat, it

is imperative that the level'be prevented froml getting too high, Vas thefioat controlled means only regulates the amountof fluid coming intoy the vat.v t n I have not shown and described the steam trap in detail, as I prefer to employ the-con-A ventional steam trap, which is indicated by the numeralQy in the drawings.
